Pharaoh made the Israelites work very hard and treated them cruelly in
other ways. God was sorry for his people, so he came to Moses and told
him to go to Pharaoh with his brother Aaron and order him to let the
Israelites go away from Egypt to a land He had made ready for them. But
Pharaoh did not care anything about what God told him to do and would not
let the people go. So God sent dreadful plagues upon the Egyptians. Still
Pharaoh was stubborn and held out against God until the tenth plague
came, which killed the eldest child in every Egyptian house. Then he sent
the Israelites out of the land.
